BLANK FOR WASHERS.

SPECIFICATION forming part of Letters Patent No. 394,538, dated December11, 1888.

Application filed February 29, 1888. Serial No. 265,738. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE H. GRIFFIN, of Abingdon, in the county of\Vashington and State of Virginia, have invented certain. new and usefulImprovements in Dies and the Product of the Same; and I do herebydeclare that the following is afull, clear, and exact-description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My invention has relation to an improved form of blank, preferablyproduced by apeculiar-shaped die or stamp, as more fully describedhereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a bottom plan viewof the die preferably employed in forming the herein-de scribed blanks.2 is a side elevation of the same, the bottom or cutting part beingbroken away; and Fig. 3 is aplan view of the blank as cut out by thedie.

In the drawings, the reference-letter A indicates the stock of a die,which is provided upon its face with a slot or groove, B, to form thebody portion of theblank This groove can be of a rectangular or circularshape to form the body portion of the product of corresponding circularor rectangular shape. A slot, E, extends transversely across the face ofthe die from one side of the slot B, across the central portion andbeyond the opposite side of the slot B, the ends of said slot extendingwithin a short distance of each other, and the cross or transverse slotextends between said ends, leaving the bridges e e between the oppositeends of the slot-body portion of the product and the sides of thetongue-forming slot for the purpose of separating the tongue and ends ofthe body portion of the blank, as shown in the blank in Fig. 3.

It will be readily seen from the foregoing description that the slot Bwill form the body portion of the blank, which is provided with the freeends, and the cross-slot will form the tongue of the blank, which isformed integral with the inner edge of one side of the body portion ofthe blank and extends across the central opening of the same, andpreferably through the space between the ends of the body portion and asuitable distance beyond the outer edge of the same.

The die is shown and described herein merely to illustrate a manner offorming the blank which constitutes the basis of the presentapplication; and I wish it understood that I do not limit myself to anypeculiar apparatus for or method of forming said blank, as I claim theblank per se and independent of the means or process by which it ismanufactured. Ialso wish it understood that in the present application Ido not claim the die herein shown and described.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is

l. The blank, as the product of the hereindescribed die, consisting of abody portion provided with free ends, and a tongue formed integral withthe body and extending across the central opening of the'same, as setforth.

2. The blank, as the product of the hereindescribed die, consisting of abody portion provided with free ends, and a tongue formed integral withand extending from the inner edge of the body portion across its centralopening and through and a suitable distance beyond the opening betweenthe free ends of the same, as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

GEORGE I-I. GRIFFIN.
